Just a few days over a year after Jodie Whittaker was first revealed as the new lead of the longrunning BBC sci-fi series Doctor Who, we finally have our first full look at what’s in store for the Thirteenth Doctor.

The trailer, released during the Doctor Who panel at Comic-Con International in San Diego, features our best look to date at Whittaker’s new Doctor and her band of companions. Joining Whittaker’s time and space-bending adventurer are Graham (Bradley Walsh), Ryan (Tosin Cole), and Yasmin (Mandip Gill Graham).

Prior to the reveal of the trailer (which you can watch above, by the way), attendees at the panel watched a few videos about this momentous debut.

This is all a big deal, quite possibly the biggest Who-related big deal since the franchise returned in 2005, since Whittaker is the first woman to ever play the Doctor in the series’ 55 year history. With the new season starting in October, the Doctor will be a woman–and that’s not the only change in the show.

Previous showrunner Steven Moffat (also known for his revitalized Sherlock series) stepped down after nearly a decade in charge. The new showrunner is Chris Chibnall, who previously worked on the Who spinoff Torchwood and the acclaimed crime drama Broadchurch (also starring Whittaker!).
